Name ? : Astatine Who discovered it ? : Dale Corson When he discovered it ?: 1940 in California, USA Symbol ?: At Atomic number ?: 85 Atomic mass ? : 210 A source of symbol ?: Just a abbreviation of the name. Probly used bacause the abbreviation was already used. Protons ? : 85 Neutrons ?: 125 Electrons? : 85 Where is it found ? : land Form ?: solid Melting point ? :302.0 °C Boiling point ?:337.0 °C Density ?: about 7 grams per cubic centimeter Abundance in the earth’s crust ?: 25 grams exists in Earth's crust at any given time. Uses ?: it is far to rare to have any uses. Some researches thank that it could possibly be used in medical ways but its is similar to Iodine. If it is simmiler to Iodine it could be used to treat certain diseases in the thyroid like thyroid cancer. It has more matallic than odine.
Fun Facts
1) Its radioactive.
2) Can be used to treat thyroid canser and
other types of thyroid diseases
3) Collects in the thyroid gland
4) It is in the Halogens family
5) There is less than 1 ounce of Astatine
in the entire earths crust and exists as a
result of uraniuma thorium decay
6) 1 ounce = 28.335 grams
